I feel pretty confident in stating here that there was no climate to gauge if one takes into account that there was no 100 billion years ago, as it would've been before the big bang (13-15 billion yrs ago) which we now consider is when time began.
Sciences say that the sun was formed 4,600,000 years ago
No, the earth wasn't around 7 billion years ago. Earth formed about 4.6 billion years ago.
8.1 billion years ago
Earth did not exist 700 billion years ago, nor did the universe. Earth is about 4.6 billion years old.
Approximately 13.8 billion years ago.
1000 years
No. As far as we know, nothing existed 75 billion years ago. The universe is about 13.7 billion years old and Earth about 4.55 billion. Dinosaurs appeared about 230 million years ago and died out 65.5 million years ago. So dinosaurs were around 75 million years ago, not 75 billion.

Approximately 2.3 Billion years ago. But it was much higher and in a colder climate then.

No, vertebra life has not existed for more than half a billion to a billion years ago. Dinosaurs first appeared about 230 million years ago and died out 65.5 million years ago.
The present best estimate is 4.6 billion years.
2.1 billion years ago
8.1 billion years ago
Earth formed about 4.6 billion years ago.
4.6 billion years ago or 5 billion years if you round up. :)
No. Plants emerged around 1.2 billion years ago, but there were photosynthesizing bacteria 3 billion years ago.
